A marathon in which the runner passes his hotel at about the twenty-third mile and thinks to himself, "I've had enough; I could catch a shower and maybe even get an early flight home," and veers off the course and stops.

John: How did Marty do in his marathon today?
Pat: He turned it into a Martython. He was a little tired as he passed the Holiday Inn at so he cut it short, took a shower, and caught an early flight home.
